Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To improve a water quality environment in a bay by forming a plane shape of a breakwater tip part through which a tide passes into a shape of being recessed in order toward the center from left and right both side surfaces of the breakwater. SOLUTION: A plane shape of a breakwater 4 tip part through which a tide 2 passes is formed in the shape of being recessed in order toward the center from left and right both side surfaces, that is, an acute angle triangular shape up to reaching a bottom part from a top part of a breakwater 4. Next, when the tide 2 passes through one side wall surface of an acute angle triangle shape of the breakwater 4, flow speed increases by an orifice effect, and increases the separating action of the tide 2 easily sticking to a wall surface of the breakwater 4. Next, in the tide 2 flowing in the breakwater 4, since a wall surface on the other one side of the acute angle triangular shape expands a passage toward the inside of a bay 5, the flow speed extremely reduces, and a large circulating flow 6 is generated in the bay 5.  Thereby, the circulating flow 6 generated on a back face of the breakwater 4 reaches over a wide range, and can eliminate a stagnant water area in the bay 5, and a water quality environment can be improved without eutrophicating.
